Frequently Asked Questions

What does the “continuous torque at standstill = 0.33 Nm” specification imply for acceleration of load in motion tasks?

It means the motor can hold about 0.33 Nm without rotating; during motion start-up you’ll need significantly higher peak torque, so inertia of load and motor must be low to ensure rapid acceleration. If load inertia is large, the motor might struggle to overcome static friction or load resistance, leading to slower start or risk of stalling.

How does having both resolver feedback and an integrated absolute encoder improve position control stability?

The resolver provides robust analog feedback under harsh conditions (temperature, vibration), while the absolute encoder preserves shaft position even after power loss, enabling faster recovery on startup. Together they enable high accuracy, minimal drift and reliable operation in precision applications.

How does the keyway shaft and absence of shaft seal affect mechanical installation and maintenance?

A keyway allows secure torque transmission to attached couplings or gears, but without a shaft seal the shaft end is exposed, making it vulnerable to dust, coolant or debris ingress; this requires environment control or additional protection. Also, in washdown or clean‐room conditions, lack of seal may reduce lifetime unless mitigated.

What are trade-offs of “without blocking brake” (no holding brake) in automated packaging systems?

Without a holding brake, you cannot rely on the motor alone to hold position when power is off or in a fault; you’ll need mechanical locks or external brakes. It simplifies design and reduces weight/cost but safety or safety‐related positioning must be addressed elsewhere.

What does “motor length code A” and “size 025 with centering diameter 40 mm” mean in terms of footprint, mounting, and inertia?

These define the physical envelope: size 025 and a 40 mm centering diameter give compact mounting compatible with interfaces for that family and limit rotor’s moment of inertia; shorter motors (length code A) have less inertia but also less cooling surface and less torque ripple dampening. Matching those to your application ensures the motor can accelerate/decelerate rapidly without overshoot.
